SPECIFICATION forming part of Letters Patent No. 437,035, datedSeptember 23, 1890.

Application filed February 15, 1889. Serial No. 299,982. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS F. MCGANN, a citizen of the United States,residing at Somerville, in the county of Middlesex and Commonwealth ofMassachusetta'have invented a certain new and useful Improvement inShow-Racks, of which the following is a specification.

, My invention relates to show-racks; and it consists in the devices andcombinations hereinafter described and claimed, the purpose of saidinvention being to furnish a convenient means of displaying goods in astore and to render said means adjustable to a great variety ofpositions. I r

In the accompanying drawings, Figure 1 is an isometric perspective viewof my invention, showing two sets of arms supported upon vertical rodsor posts; Fig. 2, a similar view of the same supported upon a verticalsurface or wall; Fig. 3, a vertical central section of one set of armssupported as in Fig. 1.

The invention herein described is an improvement on that shown in UnitedStates Letters Patent No. 394,595, granted December 18, 1888, to me.

In the drawings two different means of supporting the device are shown,the supporting means in Figs. 1 and 3 consisting of vertical posts A,provided with feet or bases resting upon and secured to any suitablehorizontal surface, as a floor or the top of a counter. On the posts Aare arranged collars b I), each held by set-screws B B, which turnradially in said collars and thrust against the posts A. The heads 19 bof the screws are made much larger than is necessary when the screws areto be used merely as set-screws to enable said heads, when desired, tobe used as supporting-plates, as shown in Fig. 2, said heads beingprovided with screw-holes 11 b through which screws 11 b may be driveninto a wall or vertical standard, as shown in said last-named figure;or, if desired, said heads or supporting-plates may, it is evident, besecured to a horizontal surface. On parallel pivots b b the arms 0O'-two in a setare pivoted to the collars b b, substantially as thecorresponding arms in said previous patent are connected to theirsupporting-plates, in such a manner as to swing freely in the same planeusually, but

not necessarily in a vertical plane. As in the patent referred to, eachset of arms 0 0, two sets being shown in Figs. 1 and 2, consists of alonger arm 0 and a shorter arm 0, the free end of said shorter arm beingconnected by a horizontal pivot c to a slide D, provided with ears d toreceive the free end of said arm and to support said pivot, said slide Dhaving a slot or hole, through which the longer arm 0 slides freely toadjust the relative positions of said arms, a set-screw d turning insaid slide and thrusting against said longer arm to hold said arms inany required position; also, as in said patent, a disk E is secured tothe free end of the long arm 0, and has a central orifice, through whicha binding-screw f is driven into a threaded hole in the center ofanother disk F to draw said disks in contact with each other, theadjacent faces of said disks being preferably roughened to prevent thedisks from turning on each other when held in contact by said screw. Thedisk F has a projecting stud f and supports the bar G, and hooks H aresupported on said bar G and in turn support rods I, substantially asdescribed in said patent, said rods I being intended for the display ofgoods hung thereon. The arms 0 O, unlike the corresponding arms in saidpatent, are each adjustable in length, each being formed in two parts,the parts 0 c in each arm nearest the collarb or b which supports itbeing a sleeve, in which slides the other part c c of said arm, bothparts 0 c of the shorter arm 0 and the sleeve of the longer arm C beingpreferably straight, while the outer portion 0 of said longer arm ispreferably curved, as shown, to prevent a view of the goods displayed onthe rods I being obstructed by goods displayed on the rods 1,

hereinafter named. The parts of the arms 0 O are held together byset-screws c c ,which turn in said sleeves c 0, respectively, and thrustagainst the parts 0 0 within said sleeves, the free ends of the sleevesbeing provided with annular bosses or enlargements c c to support saidlast-named set-screws. This construction allows the length of the arms 0C to be varied, the variation in length of the arm 0 changing theangular position of the longer arm 0 and the variation in length of saidlonger arm varying the relative positions of the rods I I. The part cmayhave notches e to receive the ends of the screws 0 To increase thedisplaying capacity of the rack, the collar or slide D is made double,and an arm C is inserted in one part (the lower part d as shown) of saidcollarD, and adjustably secured therein by the set-screw dfiwhich turnsin said lower part 01 and thrusts against said arm C and saidlastnamedarm is further supported by another collar 0 formed in one piece withthe boss 0 of the arm 0, said arms C C lying in the same planevertically. The arm 0 at its free end supports a clutch E F, which ismerely a duplicate of the clutch E F, and the stud f, bar G, rods I, andhooks H are also duplicates of the parts of the same name and designatedby the letters of reference f G, I, and H, and perform the samefunctions.

To improve the appearance of the rack when the same is supported, asshown in. Fig. 2, the set-screws B 3 are turned into the collars b 1)until the threaded shanks of said .screws are wholly concealed in saidcollars and the heads I) b of said screws rest against said collars, theholes 1) I) in said collars which receive said screws being long enoughfor this purpose, as shown in Fig. 3, where said holes extend across theopenings which receive the standards or posts A. Goods may also bedisplayed directly upon the arms 0 C The arms 0 may, if desired, beformed in two parts adjustable one within the other just as the parts 0c of the arms 0 are adjustable.

I claim as my invention 1. The combination of collars, set-screwsturning in said collars, arms pivoted to said collars, andmeans,substantially as described, of adjustably securing the free end ofone of said arms to the other of said arms, said setscrews havingenlarged heads provided with screw-holes to enable said heads to be usedas supporting-plates for said arm or at will to enable said collars tobe adj ustably secured upon a standard, as and for the purposespecified.

2. The combination of a standard, collars adapted to receive saidstandard, set-screws turning in said collars, arms pivoted to saidcollars, and means, substantially as described, of adjustably securingthe free end of one of said arms to the other of said arms, saidsetscrews having enlarged heads to enable said heads to be used asattaching-plates, and supporting-plates for said arms when said collarsare removed from said standard, as and for the purpose specified.
